[marcdaven]

Mga bro, naa koy problem bah.

I have this C program and I need to perform the square root operation para sa area of a triangle using Heron's formula. Mao ning program nako ay:

#include<stdio.h>
#include<conio.h>
void main(void)
{
 int a, b, c;
 float s, dividend, area;
 clrscr();
 printf("Enter 3 numbers separated by space for the sides of the triangle: ");
 scanf("%d %d %d", &a, &b, &c);
 s=(a+b+c)/2;
 dividend=s*(s-a)*(s-b)*(s-c);
 if (dividend<0)
  printf("The given sides do not represent a triangle");
 else
 {
  area=????????
  printf("Area of the triangle: %.2f", area);
 }
 getch();
}

Thanks mga Bro!
